//该代码是基于网路代码简单修改过一点点 (等于没改) 主要用来做个笔记

    this.triggerEvent(“timePicker”, times) 用于组件传值 接收就用 bind:timePicker=”自定义方法名”

    1. <picker class="pa" mode="multiSelector" bindchange="bindMultiPickerChange" bindcolumnchange="bindMultiPickerColumnChange" value="{{multiIndex}}" range="{{multiArray}}">
    2.   <input value='{{time}}' placeholder='请选择时间' />
    3. </picker>
